Answer:
1.2% of 250
Step-by-step explanation:
Step 1: We make the assumption that 250 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%-250.
Step 4: In the same vein, x%=3.
Step 5: This gives us a pair of simple equations:
100%=250(1).
x%=3(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / x%= 250/3
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100% =3/250
x=1.2%
Therefore, 3 is 1.2% of 250.
